Siemens Building Technology 257-02055 Valve Assembly 323613-751 allowing technicians to fine-tune ducting

allowing technicians to fine-tune ducting static pressure or filter status monitoring

and ensure a dry nitrogen purge to prevent oxidation inside the lines

Contractors often identify failure through excessive bearing noise (screeching/grinding)

Engineered with a capacitance range of 540-648 MFD and rated for 110/115Vac

While the cast aluminum case is rugged

Siemens Building Technology 257-02055 Valve Assembly 323613-751 allowing technicians to fine-tune ductingThe Siemens 257 02055 Valve Assembly is a high performance 2 way normally open valve designed for precision control of hot or chilled water and low pressure steam in terminal units. Built on the rugged Powermite 599 MT Series platform, this assembly features a 1 2 inch NPT connection and a 2. 5 Cv flow coefficient. The forged brass body is paired with stainless steel trim to ensure long term durability and resistance to scaling in demanding hydronic
